This class is aimed to provide a dummy storage object, useable for stuff like mailback forms. Usually, you won't save datamanagers running with this storage backend, accessing the types values directly. The type's convert_to_storage helper functions can be a nice help if you need string representations.
Special care has to be taken when attachments are being used with this type. Since $object is always null by default, types working on attachments must create a temporary object before going on. This implementation does not work with such an object instance for any data i/o operations except those invoked by the types directly on it. This especially means, that any store operation will still fail on this implementation for all regular types not working on $object directly.
Also, there is no code whatsoever involved, which does the transition of a temporary storage object through multiple requests. You need to set $object accordingly yourself.
\midcom_helper_datamanager2_schema&$schema The data schema to use for processing.
arrayThe defaults to use as "artificial" storage. This can be omitted safely.
null is used for unset defaults.
